The A19 Tees Viaduct or Tees Flyover is a six-lane dual carriageway road bridge in the North East of England carrying the main A19 trunk road north-south across the River Tees. It is situated between Middlesbrough and borough of Stockton-on-Tees just north of the A19's interchange with the A66 trunk road. The Teesdale Way long-distance footpath, the Tees Valley Line, the B6541 (Old A66/A67, Stockton Road) and the A66 pass under the bridge on the southern bank of the Tees. == Design == The viaduct is a beam or girder bridge. It has reinforced concrete piers and pier bends supporting steel-plate girder beams and a composite deck with some 200 moving parts. The viaduct is 2.9 km long〔(【引用サイトリンク】work=Bridges on the Tyne )〕 and 1.95 km between abutments〔???〕 and was at the time the largest such bridge in the British Isles.〔(【引用サイトリンク】url=http://www.cycle-routes.org/threerivers/3r_bridges/tees_bridges.html )〕 It has 68 spans on the main north south route—the largest span being that over the river at 117 m. The bridge was designed with sufficient clearance to allow ships to pass, although the port of Stockton-on-Tees up-river was virtually redundant by then.〔(【引用サイトリンク】work=Bridges on the Tyne )〕 Since the Tees Newport Bridge had its lifting deck permanently fixed in the down position in 1990, large shipping can no longer reach the Tees viaduct, further reducing the need for such a high structure. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Tees Viaduct」の詳細全文を読む スポンサード リンク
